NICHOLAS WARRELL, OF FARRAGUT, IONVA.

HINGE-JOINT FOR ELECTRIC BELTS.

SPECIFICATION forming part of Letters Patent No. 399,954, dated March 19, 1889.

Application filed October 1'7 1883- Serial No. 288,848. (No model.)

To all whont it may concern:

Be it known that I, NICHOLAS WARRELL, a citizen of the United States, residing at Farragut, in the county of Fremont and State of Iowa, have invented certain new and useful Improvements in Electric Belts; and I do hereby declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in electric belts; and it consists of the peculiar construction and arrangement of parts, as will be hereinafter fully described, and particularly pointed out in the claims.

My invention relates more especially to a brace or stay for strengthening the plates or elements of the cells of an electric belt, and which is also constructed to form a hingejoint between the several elements or plates of the series of cells. By constructing the hinge to serve as a brace or stay to the plates or elements, as well as to secure a flexible joint, I am enabled to materially strengthen the parts and produce a belt which is superior in points of durability, strength, and simplicity of construction.

lVith these ends in View my invention consists, essentially, of a hinge-section bent from a single piece of Wire to form two spaced eyes or loops, which are connected by an intermediate arm or bar arranged at one side of the vertical plane of said eyes to leave a space or seat, into which one end of the plate or element of a cell is tightly fitted, whereby the end of the plate to which the hinge-section is connected is materially strengthened and braced by the wire which forms the hingesection, all as will be more fully hereinafter described.

In the accompanying drawings, Figure 1 is a perspective view of a plate or element having a section of a hinge embodying my invention. Fig. 2 is a detail longitudinal sectional Fig. 3 is a detached detail view of the wire after it is bent to make the hinge-sec tion. Fig. 4 is a central sectional view through a series of cells of which the belt is made.

Referring to the drawings, in which like letters of reference denote corresponding parts in all the figures, A designates a plate or element of an ordinary electric belt, on which no novelty is herein claimed.

In carrying my invention into practice I perforate said plate or element at both ends with two apertures, (designated by the letters CLCL and b b, respectively,) through which are passed the ends of the wire from which a hinge-section, C, is bent. This hinge-section O is made from a single piece of wire, which is first bent upon itself at an intermediate point of its lengthinto an eye or loop, cl. Said wire is then bent at right angles to said loop (Z, to provide an arm or bar, 6, and it is then again bent upon itself to form another eye or loop, f, corresponding to the eye or loop These eyes (Z f are arranged in the same vertical plane, while the arm or bar 6, which connects them, is arranged at one side of the eyes or loops, as shown. The ends of the wire are arranged parallel with each other, as shown at g g, and the arm or bar 6 is bent laterally a short distance to one side of said parallel arms g g, whereby a space or seat, h, is pro vided between said arms g g and the connecting cross arm or bar c, into which one end of the plate or element is fitted when the wire is connected to the plate, my preferred way of accomplishing which I will now proceed to describe.

One end of each arm g g is first passed along one face of the plate or element A and through the apertures a a to the opposite face of the plate, and then through the apertures Z) Z) in the opposite end of said plate, and thereby returned to the same side or face of the plate or element, the ends being finally pressed or forced close against one face of said plate or element. It will be noted that the wire arms g g bear against both faces or sides of the plate or element, and that they are securely connected thereto. The eyes or loops (Z f are arranged near the middle, at one end, of the plate or element, and the latter is firmly pressed or forced into the seat or space h between the cross-bar c and the bars 9 g. By thus forcing the plate or element into the seat h in rear of the eyes or loops the bars 6 and g g are made to serve as stays or braces to the end of the plate or element, -which thus materially stiffens and strengthens the plate or element at the point where the greatest strain is exerted thereon, owing to pull of the plates or elements on the flexible joints.

In Fig. 4 of the drawings I have shown a series of cells, 1 2 3 4, each of which is composed of two elements-copper and zinc, respectivelyand an interposed absorbent pad adapted to be saturated with an exciting liquid or fluid.

The positive element of one cell is connected with the negative element of the cell adjoining the same, as is usual in this class of devices, and the elements and interposed pad of each cell are suitably bound or secured together by any preferred fastenings.

Slight changes in the details of construction and form and proportion of parts can be made without departing from the spirit of my invention.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an electric belt, a hinge-section made of wire and having the spaced eyes or loops, the cross-bar, and a seat formed at a point in rear of the eyes or loops, and a plate, to which said hinge-section is connected, fitted tightly in said seat, substantially as described, for

' the purpose set forth.

2. In an electric belt, a plate or element and a hinge-section secured to said plate and having one end thereof extended beyond the plate, said hinge-section having a seat into which the end of the plate or element is tightly fitted, substantially as described, for the purpose set forth.

3. In an electric belt, a plate or element and a hinge-section bent from a single piece of wire and consisting of the spaced eyes or loops, the parallel arms, and a cross arm or bar arranged at one side of said parallel arms and in rear of the eyes to form a space or seat for the reception of one end of said plate, substantially as described, for the purpose set forth.

4. In an electric belt, a plate or element having the perforations a a and b b, and awire hinge-section having a seat formed between its bars 9 g and the cross-bar c at a point in rear of the loops, said arms g g being passed through the perforations and resting against opposite faces of the plate, substantially as described, for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

NICHOLAS WVARRELL.
